purpose: to report three cases of alport syndrome in one family with anterior lenticonus and retinal flecks. patients and findings: three members of one family with consanguineous parents are presented who had renal and ocular involvement. they had anterior lenticonus and a beaten bronze appearance in the macula. reduced visual acuity and photophobia were the chief complaints of these patients...
We report a case of a 58-year-old man presenting with a spontaneous and late in-the-bag intraocular lens dislocation to the vitreous. A previous uneventful extracapsular cataract extraction with can-opener style capsulotomy and implantation of a polymethylmethacrylate three-piece lens was performed and, two years after the surgery, the patient developed capsule contraction syndrome with a fibro...
Oxygen permeability and water diffusion characteristics were determined for several types of hydroxyethyl-methacrylate hydrophilic contact lenses and a silicone contact lens material. A twoto fourfold difference in the diffusion rates for capillary flow of water was found among the different hydrophilic lenses. Oxygen permeability studies demonstrate that the hydrophilic lenses are capable of t...
This article compares methods of axial length measurement for determining intraocular lens power and describes bimanual micro incision phacoemulsification for refractive lens exchange and routine cataract surgery, which offers an enormous advantage of maintaining a more stable intraocular environment during lens removal. This advantage may be especially important in high myopes who are at a gre...
PURPOSE To report hydrophilic acylic intraocular lens (IOL) opacification after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) in an eye with multiple prior intraocular surgeries and iatrogenic aniridia. CASE REPORT A 34-year-old woman with history of penetrating keratoplasty (PKP) for advanced keratoconus and subsequent Urrets-Zavalia Syndrome (UZS) underwent phacoemulsificati...
BACKGROUND To evaluate the rotational stability of the three types of AcrySof SA60TT toric intraocular lenses (Alcon, Switzerland) in cataract surgery after the first postoperative week. METHODS A retrospective study of 44 eyes in 33 patients. All patients underwent similar uncomplicated phacoemulsification cataract surgery. Seven eyes with corneal astigmatism of less than 1.5 D were implante...
AIM To assess the accommodative power of a new foldable monofocal intraocular lens. METHOD A prospective randomised non-masked clinical interventional study. The study included 40 patients attending the hospital for cataract surgery and who were randomly distributed into a study group receiving a new foldable monofocal intraocular lens with flexible haptics, and a control group receiving a st...
